((31. 248-243) This invention relates to architecture, to themanner of constructing buildings of and to the equipment employed insuch production utilizing materials of many kinds at various locations.

The invention relates particularly to scafiolding used on buildings ofall kinds especially during construction and for the supporting ofworkmen both on the interior and the exterior of such buildings tosimplify and facilitare the handling of materials while construction isin progress.

This application is a continuation-in-part of application 26,847 andcontains additional subject matter disclosed in applicants priorapplication 104,620.

In the construction of buildings including split level and two-storystructures much time and material has been sacrificed in the erection ofscafiolding on the interior to simplify and facilitate the handling ofmaterials such as joists, rafters, roof trusses and the like, and on theexterior to install sofiit, facia, sheathing, siding, windows and thelike. Ladders and other prefabricated structures have been employed inan attempt to accelerate production and to reduce Waste material, butthe result has not been satisfactory or safe, particularly with modernconstruction employing soft fiber wall sheathing through which a ladderwould readily break.

It is an object of the invention to overcome the problems enumerated andto provide simple, inexpensive and safe scaffolding for use in buildingconstruction and which can be suspended and thus not be influenced byvariations in the topography of the terrain.

Another object of the invention is to provide scaflolding including asuspension frame with special supporting brackets or jacks which can bemounted on and suspended from such frame either on the interior orexterior of a house and which can be installed and removed in a minimumof time by a single individual and repeatedly used.

A further object of the invention is to provide a single frame of partswhich can be readily taken apart and compactly arranged for shipment.

A still further object of the invention to provide scaffolding includinga suspension frame supported by a building under construction and havingcross rods of a length to span two adjacent studs.

Briefly stated, the invention is a safely scaffolding support for use inthe construction of a building and comprising a rfirame adapted to bedisposed in upright position, either suspended from the top or otherportion of a building or allowed to rest on the floor. One or more crossrods are mounted on the frame and are of sufiicient length to span atleast two of the upright studs of the building. A shoe having aplurality of notches in its upper surface is mounted on the frame andsuch shoe is adapted to penetrate the soft fiber insulating sheathing ofthe building to support a triangular shaped bnacket or jack which inturn support the platform forming members.

With continued reference to the drawings, a building is provided havingstuds or uprights 10 connected by top and bottom members 11 and 12attached to the floor 13 and having soft pliable wall board or sheathing14 on the exterior of the studs 10. The studs or uprights of an outsidewall generally are constructed on 16" centers unless the wall is notload bearing, in which event sometimes the studs may be located on 24"centers.

The present invention contemplates a safety scafiolding support having asingle suspension from or hanger 15 with a hook 16 at its upper end anda series of adjustable openings 17 along its length. Mounted forlengthwise adjustment on the hanger 15 is a sleeve 18 having a notch 19in its lower end for reception of a pin 20 located in one of theopenings 17 in the hanger 15, thus non-rotatably mounting the sleeve 18.Integral with the sleeve 18 is carried an arm or shoe 21 having notches22, one of which is adapted for the reception of a pin 23 connecting apair of spaced plates 24 connecting horizontal and vertical legs 25 and25 joined at their outer ends by the third or longer leg 27 of atriangular bracket or jack, the leg 27 having a hollow extension 28 fora purpose hereinafter described. A pair of cross braces 29 havingthreads on both ends are threaded into a coupling 26 that is Welded orotherwise afi'ixed to the upright leg 26 at right angles to the plane ofthe triangle and adjacent its lower end, the outer ends of the crossbraces 29 being provided with threaded caps 29'. When the pin 23 islocated within the slot 22 of the shoe 21, the cross braces 29 areadapted to engage yoke brackets 39 carried on the outer ends of crossbrace 32 welded or otherwise affixed to a sleeve 31, the sleeve 31 beingprovided with notches 33 in its opposite end for reception of pins 34identical with the pins 20. The cross brace 32 bears against the innersurfaces of at least two of the studs 10 (FIG. 6) and the yoke bracketsare engaged by the cross braces 29 to provide lateral sup- 3 port forthe lower end of the jack. By providing notches 33 in the opposite endsof the sleeve 31 either end of the sleeve may be above the other end andthe cross brace 32 may be disposed on either side of the frame 15.

By using a pair of the supports in spaced relation, a platform 35 may besafely supported on the horizontal legs 25 of the jacks. Retainers 36may be welded to the horizontal members 25 to prevent the boards whichconstitute the platform 35 from slipping laterally. In order to providea safety guard the tubular members 28 may be provided with uprightmembers 37 having an eye 38 in the outer end in which a guard rail 39may be received.

In FIG. 8 the safety scafiold support has the hanger supporting sleeveand shoe on the interior with the shoe projecting outwardly through thewall of the building. The sleeve 31 with the cross brace 32 is mountedwith such cross brace between the hanger 15 and the inside of the studs10 to withstand any pull on the shoe 21 by means of weight on the boardswhich form the platform 35. In FIG. 8 the scaffolding is installed on aflush type wall, while in FIG. 10 the wall has an offset in both casesthe cross braces 29 carrying caps 29' resting against the surface of thewalls to provide lateral support for the lower end of the jack.

In FIG. 11 the hanger is inverted so that the hook 16 rests upon thefloor 13 and the sleeve 18 carrying In FIGS. 14 and 15 the safetyscaffold support is the same as that of FIGS. 1-10 except that the hook62 at the top of the hanger is different from the hook '16 in theearlier figures and the sleeve 18 which carries the hook 21 is providedon the side opposite the member 21 with a sleeve 63 in which is mounteda removable brace 64 adapted to be secured within such sleeve by meansof a pin 65.

In FIG. 18 a sleeve 31' with a yoke is provided with a sleeve 66 forreceiving a removable brace 67 adapted to be secured in fixed positionin the sleeve by means of a pin 68. Such structure facilitates andenlarges the usefulness of the device as illustrated particularly inFIGS. 14 and 15. When the triangular bracket or jack is supported withinthe building as illustrated in FIG. 14, the sleeves 63 and 66 aredisposed between the studs 10 and the braces 64 and 67 are omitted. Thebrace 29 on the triangular bracket spans two of the studs 10 andprevents outward movement of the frame 15. When the bracket is supportedon the outside of the build ing as illustrated in FIG. 15, the braces 64and 67 are attached to the sleeves 63 and 66-respectively and span twoof the studs 10 to prevent outward movement of the the shoe 21 issupported at any desired elevation by means of the pin 2%, such shoeprojecting through the wall similarly to that of FIGS. 8 and 10. Inorder to stabilize the member 15 in its upright position, a pair ofsleeves 4% similar to the sleeves 31 may be provided and such sleevesare retained by pins 41 similar to the pins 34. Each of the sleeves 41Bis provided with a. cross brace 42 having externally threaded endportions 43 on which are received adjusting nuts 44, each having acylindrical portion with an enlarged flange with the .cylindricalportion adapted to bear against the inside surface of a stud and theflange to engage the side of the stud to prevent axial movement of thebrace 42 and consequently the hanger 15, a pair of such braces 42 beingemployed in spaced relation, with one above and one below the shoe 21.Thus the shoe 21 will be held firmly in a fixed position to support ajack thereon exterior of the wall through which such shoe projects.

In FIGS. 12 and 13 a relatively short upright member or frame 45 isprovided having openings 46 for the reception of pins 47 by means ofwhich a sleeve 18 of a shoe 21 is adjustably mounted. The frame 45 isprovided with a foot 48 having a sleeve 49 in which one end of suchframe is received and fastened thereto by means of a pin 5% The foot 48has an upright flange 51 which fits flat against the lower member 12 andthe outer corners of the foot 48 are provided with struck down portions52 to engage the floor 13 and prevent lateral slippage of the footthereon.

At its upper end, the upright member 45 is received within a sleeve 53held in vertically adjusted position on the frame 45 by means of the pin54. Welded or otherwise secured to the sleeve 53 is an angle bracehaving a vertical wall 55 and a horizontal wall 56, the vertical wall 55having multiple spaced prongs 57 which engage a horizontal wood brace 58secured between the studs 10 by means of nails or other fasteners 59.With this construction the shoe 21 projects through the wall the same asin FIGS. 8, 10 and 11 and the prongs 52 and 57 prevent any lateralmovement of the upper and lower ends of the support 45 and the flanges51 and 55 will resist outward movement of the shoe.

In FIG. 13 the safety supporting structure of FIG. 12 is employed whereinstead of the member 58 being located between the studs 11 a crossmember 60 is secured by fasteners 61 to the inner surface of the studsand consequently the foot 48 is reversed to space the lower end of thesupport 45 from the bottom member 12.

frame 15.

In FIG, 17 there is disclosed a pair of shoes 69 mounted on oppositesides of a sleeve 70 having a slot 71 in its lower end for receipt of amounting pin in one of the upright hangers or supports, the shoes 69being provided with slots 72 and 73 inclined toward the sleeve andadapted to receive the pins 23 of the platform supporting brackets orjacks, thus providing a construction by which a platform may besimultaneously provided on both sides of a wall.

In FIG. 19 is disclosed a mounting bracket 74 in the form of a channelmember with penetrating prongs 75 adapted to pierce a cross member 76 ofthe building. The mounting bracket 74 has welded or otherwise affixedthereto a shoe 77 with slots 78 for receiving the corner pin 23 of asupporting jack, the shoe 77 being provided with opposed angular braces79, the structure of FIG. 19

being particularly appropriate for the outside of a buildmg.

In FIG. 20 another means is illustrated for mounting one or more jacksor brackets on a cross member 80, such member comprising a channelmember 81 having prongs 82 adapted to penetrate the cross member and tothe channel member 81 are attached horizontal and vertical shoes 83 and84 respectively, the horizontal shoe 83 with a slot 85 and the verticalshoe 84 with multiple slots 86, each of the shoes 83 and 84 being weldedor otherwise affixed to the channel member 81 and the shoe 83 having apair of opposed reinforcing brackets 87 and a pair of similar brackets88 being employed for securing the shoe 84 to the channel member, thusproviding for mounting of a jack or scaffold supporting bracket eitheron the interior or the exterior of a wall by the application of thechannel member in the manner illustrated in FIG. 19 or in the mannerillustrated in FIG. 20.

With reference to FIGS. 21-27 a further modified form of the inventionis disclosed and includes a safety suspension frame having a pair ofspaced substantially parallel upright members or rods connected by aseries of cross bars 116. The cross bars 116 extend outwardly of therods 115 a distance sufficient to span any conventional pair of uprightstuds 10. Each of the upright rods 115 has a transverse hanger plate 117welded or otherwise attached to the upper end thereof, and such plateshave depending hook-forming projections 118 at each of their free ends.

The plates 117 are adapted to engage the top member or plate 11 with oneof the depending projections 118 disposed exteriorly of the sheathing 14to support the sus pension frame. Near the bottom of each of the uprightrods 115, a shoe 119 is welded or otherwise attached and is providedwith notches or recesses 120 (FIGS. 23 and 26) in the upper edgethereof.

In order to support scaffolding 122 on the suspension frame, a platformsupporting member or jack 121 is provided and includes a pair of spacedtriangular brackets each of which has legs 126 and 127 of equal lengthand a third leg of greater length forming the hypotenuse of thetriangle. The legs 126 and 127 of each bracket are joined at rightangles to each other and the brackets are connected in parallel relationby braces 129 welded or otherwise attached to the outer ends of suchlegs. The brackets of the jack 121 are spaced apart a distance slightlyless than the spacing of the suspension frame and to the right angularcorner of each bracket is welded or otherwise attached an L-shapedmember 130 (FIGS. 3, 4 and 5) having notches or recesses 131 along oneedge and such L-shaped members are connected by a cross rod 132. A pairof hooks 133 are pivotally mounted on the cross rod 132 intermediate theL-shaped members 130 and are adapted to engage one of the cross bars 116(FIGS. 5 and 6) of the suspension frame to support the jack 121 on theinside of the building. When the jack 121 is applied to the suspensionframe 115 one of the legs 126 or 127 will be parallel to the sheathing14 and studs 10 and the other leg will be disposed in substantiallyhorizontal position and projecting outwardly therefrom. Each of the legs126 and 127 have stops 134 permanently attached thereto between whichscaffolding 122 may be placed and maintained in position.

As illustrated in FIG. 23, when the jack 121 is to be placed on theoutside of the wall to which sheathing 14 has been applied, thesuspension frame is mounted on the inside of the wall with the crossbraces 116 engaging at least one of the studs 10 and the shoes 119 arecaused to penetrate the sheathing 114 so that they extend to the remoteside thereof. The cross rod 132 of the jack 121 is seated in the recess120 of the shoe 119 with the legs 126 of the jack being in the uppermostposition to facilitate the installation of the sofiit, facia, and upperportions of siding, etc.

If desired the suspension frame may be reversed so that the shoes 119extend inwardly of the building and the jacks may be reversed so thatthe leg 127 is uppermost with the L-shaped member 131 extendinginwardly. Such L-shaped member is adapted to penetrate the fibersheathing 14 and selectively engage one of the cross braces 116 asillustrated in phantom in FIG. 26.

If the jacks 121 are to be located at a lower position on the outside ofthe building as shown in FIG. 24 the suspension frame may be invertedand hanger plate 117 allowed to rest on the floor 13. The suspensionframe is held in its upright position by the cross bars 116 restingagainst the studs 10.

As illustrated in FIGS. 25 and 26, when the jacks are to be mounted onthe inside of the building the hooks 133 are pivoted upwardly to engagethe cross bars 116 and the cross braces 129 engage the upright rods 115to provide a firm support for the scaffolding 122 on the outwardlyextending leg.

It will be apparent from FIG. 25 that the jacks 121 may be located oneither the inside or the outside of the building or both simultaneously.

It will be apparent from the foregoing that a relatively simple,inexpensive, easily usable structure is provided by which a piatform forworkmen may be had, and that such scaffold supporting structure easilymay be instailed, removed and packaged into a compact package forshipment; that applicants structure provides maximum safety and isreadily applicable to various types of walls.

It will be obvious to those skilled in the art that various changes maybe made in the invention without departing from the spirit and scopethereof and therefore the invention is not limited by that which isillustrated in the drawings and described in the specification, but onlyas indicated in the accompanying claims.
